The Fontana Days Run is celebrated globally as a premier event and is designated by the USATF as the World’s Fastest Half Marathon Course. This distinguished race takes place from the elevated San Bernardino National Forest to Fontana City Hall, providing participants a unique opportunity to set personal records or qualify for major races due to its downward slope. Catering to athletes of all ages and skill levels, the event also features additional activities such as a 5K Run, 5K Race Walk, 5K Family Fitness Walk, and a Children’s Half Mile Dash, ensuring fun and engagement for the entire family.
